In practical application, because the positions of the inlet and outlet of the conveyed materials are changed along with different production lines and different material types, the vibration impact generated when the materials enter the conveying line can be borne by different positions of the mounting bracket on a long strip-shaped integral conveying line, and more supporting feet or reinforced supporting devices are required to be arranged at the positions. Most of chain machines directly adopt a structure that the supporting feet are locked and fixed on the mounting bracket through bolts at the positions where the positioning mounting holes are formed in advance, so that the positions of the supporting feet cannot be adjusted adaptively according to actual conveying scenes or changes of conveyed products, and certainly the conditions cannot be met. Although a small part of chain machine also considers the requirement that the position of the supporting foot needs to be changed in the practical application process, the mode that a plurality of mounting holes are formed in the mounting bracket is still adopted, so that the supporting foot needs to be detached from the mounting bracket and then remounted when the supporting foot is adjusted.

Detailed Description
The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.
The scheme is realized by the following technical means:
example (b): in this embodiment, a novel chain machine equipment is provided, can guarantee supporting reliability and operation transport stability simultaneously, according to the change of practical application environment or the difference of transported substance product characteristics, carry out rapid, efficient control and regulation to the position of connecting supporting foot 3 between mounting bracket 2 and the ground.
For the chain machine equipment provided in the scheme, two sides of the chain machine equipment are respectively provided with an adjustable positioning supporting mechanism of the chain machine, the mechanism is similar to a common chain machine in that the mechanism comprises a connecting mounting frame 2, and a conveying belt 1 and supporting feet 3 are respectively arranged on the upper side and the lower side of the connecting mounting frame 2. The connecting mounting frame 2 is in a slender and straight rod state as a whole, and the connecting mounting frame 2 is hollow and has openings at two ends. The two ends of the connecting and mounting frame 2 near the upper part are respectively provided with a roller mechanism, and the annular conveyer belt 1 simultaneously surrounds the rollers of the roller mechanisms arranged at the two ends, so that the conveyer belt 1 drives the material part placed on the upper surface of the conveyer belt or the plate for bearing the material part to move in a translation way from one end of the chain machine to the other end while rotating. Of course, the conveyor belt 1 may be a belt made of elastic rubber material, or a metal chain belt formed by a plurality of metal chain links hinged to each other. The conveyer belt 1 is arranged on the connecting mounting frame 2 in the adjustable positioning supporting and jacking mechanisms on the two sides in the above mode, the driving device 4 is fixedly mounted between the adjustable positioning supporting and jacking mechanisms on the two sides, and the conveyer belt 1 can be driven to continuously rotate by the driving motor through the matching connection of a series of gear tooth transmission mechanisms in a transmission manner.
In the scheme, the optimized improvement of the chain conveying transmission structure part is not the key point, so that the working principle of the part of the structure is simply explained and is not unfolded.
In contrast, the main point of the present embodiment is the connection structure between the connection mounting frame 2 and the support leg 3. The functional structure is divided, and the adjustable positioning supporting and jacking mechanism of the chain machine comprises a supporting and bearing unit A for realizing the supporting function of the supporting foot 3 on the connecting and mounting frame 2 in the vertical direction and a positioning and locking unit B for realizing the locking and fixing of the supporting foot 3 at different positions along the extending direction of the connecting and mounting frame 2; the supporting and bearing unit a and the positioning and locking unit B are arranged between the supporting foot 3 and the connecting and mounting frame 2.
In the supporting and bearing unit a, a supporting bottom part formed on the lower side of the connection mounting frame 2 and a supporting top part formed on the upper side of the supporting leg 3 are included, and the supporting effect of the supporting leg 3 on the connection mounting frame 2 in the vertical direction is realized through the mutual abutting action between the supporting top part and the supporting bottom part. And in the location locking unit B, include the spacing cooperation portion formed on the said connection mounting bracket 2 and form the spacing block part on the said supporting foot 3, through the mutual butt effect between the said spacing block part and the said spacing cooperation portion, realize the said supporting foot 3 is fixed in the plane along the fixed effect of locking of the extension direction of the connection mounting bracket 2 relative to the said connection mounting bracket 2.
Specifically, for the supporting bearing unit a, a guide mounting groove 2a having the same direction as the whole extending direction of the connection mounting frame 2 is formed at the bottom of the connection mounting frame 2 which is in a shape of a long and thin hollow tube and has two through ends, the cross section of the connection mounting frame 2 is in a shape of an inverted U with a downward opening, and meanwhile, the hollow area inside the connection mounting frame 2 is also communicated to form a part of the guide mounting groove 2 a. When the connection mounting frame 2 is placed on the upright support leg 3 in this state, the bottom surface of the connection mounting frame 2 as the support bottom and the top surface of the support leg 3 as the support top abut against each other, and a supporting effect is exerted on the upper side member. The number of support feet 3 arranged on the underside of an elongated connection frame 2 and the actual installation position can be selected according to its actual length.
For the positioning locking unit B, the friction effect generated after the limit matching part on the connecting mounting frame 2 and the limit clamping part arranged on the supporting leg 3 are mutually abutted is utilized, so that the supporting leg 3 is fixed at a specific required position relative to the connecting mounting frame 2 and does not move any more. The position limiting engagement part is not integrally connected and fixed with the main body part of the supporting leg 3, but is arranged on a movable part close to the upper side of the supporting leg 3 because the control is needed to realize the conversion between the moving state and the locking state of the supporting leg 3 relative to the connecting and mounting frame 2.
Structurally, the positioning and locking unit B comprises at least a first limit coupling assembly 7 mounted on the support foot 3 and a portion of the coupling mounting frame 2. The first limit component comprises a limit connecting piece 7a which is arranged at the upper part of the supporting foot 3 in an adjustable and movable mode, and an adjusting connecting piece 7b which is used for changing the position state of the adjusting limit connecting piece 7 a.
Specifically, for example, a flat engaging plate member, which is located in a hollow region inside the connection-mounting upper guide-mounting groove 2a and whose outer peripheral surface has a variable distance from the center connection point of the through-hole at different positions, may be selected as the stopper link 7 a. The adjusting connecting piece 7b is integrally in a rod shape which is vertically arranged, the lower end part of the adjusting connecting piece is connected with a driving section with a larger radial size, and a thread structure or a concave-convex part is formed on the driving section so as to drive the adjusting connecting piece 7b and a clamping plate fixed on the adjusting connecting piece 7b to rotate together as a whole. The adjusting connecting piece 7b is passed through the main body part of the supporting leg 3 from bottom to top and then is connected and fixed on the central connecting point of the clamping plate by welding or bonding. When connecting the installation, can be earlier put into the inside of direction mounting groove 2a with a state that the size is less in the horizontal left and right sides orientation as spacing connecting piece 7a, be the drive section that rod-like regulation connecting piece 7b leaned on through rotating this moment, just can make the block plate rotate to the great state of size in the horizontal left and right sides orientation, until the outer peripheral face of block plate and the internal face inseparable butt of direction mounting groove 2a are fixed, through the frictional force that mutual butt department produced this moment, just realized fixing for the locking of direction mounting groove 2a extending direction to supporting foot 3. When the position of the supporting foot 3 needs to be changed and adjusted, the supporting foot 3 can be changed into a relaxed adjustable state only by reversely rotating the adjusting connecting piece 7b, and the supporting foot 3 can be conveniently and quickly moved and adjusted.
In view of the above-mentioned stability of the support leg 3 in the supporting unit a relative to the connection mounting frame 2 and in order to prevent the excessive supporting force of the limiting engagement portion on the limiting connection member 7a on the connection mounting frame 2 from deforming the connection mounting frame 2 during the locking and fixing of the support leg 3 by the rotation adjusting connection member 7B, another more preferred structure form may be adopted for the positioning and locking unit B.
Specifically, similar to the aforementioned connection mounting bracket 2, a guide mounting groove 2a is formed in a lower portion of the connection mounting bracket 2 having a shape of a slender hollow rod, and further, both sides of a lower end portion of the guide mounting groove 2a extend inward to form an adduction connection section 201. The inward-contraction connecting section 201 is connected with the end part of the connecting installation frame 2 which originally extends downwards, a supporting bottom with a larger area is formed, and the bearing stability between the supporting foot 3 and the connecting installation frame 2 is improved. Further, a clamping plate member, which is also flat, is selected to be disposed inside the guide mounting groove 2a, wherein when the clamping plate member is rotated to any angle position, the width dimension of the clamping plate member in the horizontal left-right direction is larger than the width of the opening portion of the guide mounting groove 2a, and a through hole extending in the vertical direction is further formed in the center portion of the clamping plate member. And for the adjusting connection 7b, a pair of mutually corresponding bolts and nuts are selected. When the nut is installed, the nut needs to be fixed on the upper surface of the clamping plate through the clamping groove matching structure, so that the nut is prevented from rotating relative to the clamping plate. Of course, if the process conditions and the cost are allowed, the function of the nut structure and the engaging plate may be directly integrated by directly providing the screw inside the through hole of the engaging plate or integrally forming the nut portion on the upper portion of the engaging plate.
After the matching and positioning of the nut and the clamping plate are completed, the bolt sequentially penetrates through the upper parts of the supporting legs 3 and the through holes of the clamping plate from bottom to top in an inverted state and then is preliminarily screwed, connected and fixed with the nut. In this state, a gap region exists between the lower surface of the engaging plate and the upper surface of the main body of the support leg 3, and when the height of this gap region is larger than the thickness of the aforementioned adduction joint 201, the engaging plate serving as the stopper link 7a, the bolt and nut serving as the adjustment link 7b, and the main body of the support leg 3 can slide inward into any position of the connection mount 2 from the one end opening of the connection mount 2. In this state, the adduction connection section 201 is positioned just in the clearance area between the lower surface of the engagement plate and the upper surface of the main body of the support leg 3.
After the position of the supporting leg 3 in the extending direction of the connecting mounting frame 2 is adjusted, the bolt serving as the adjusting connecting piece 7b only needs to be continuously rotated, and the nut can move towards the large end part below the bolt, so that clamping and fixing effects among the clamping plate between the end part of the nut and the end part of the bolt, the inward contraction connecting section 201 and the top part of the main body of the supporting leg 3 are achieved. With this structure, the lower surface of the engaging plate and the upper surface of the supporting leg 3 simultaneously serve as a limit engaging portion, the upper and lower surfaces of the inside retracting connecting section 201 simultaneously serve as corresponding limit engaging portions, and a part of the supporting leg 3 is held between the upper and lower sides of the inside retracting connecting section 201, thereby fixing the supporting leg 3 to the connection mounting frame 2 at a desired position. Since the bottom surface of the engaging plate member and the top surface of the supporting leg 3 are sandwiched by the inward contracting connecting section 201 which is completely solid and extends inward, even when a large clamping force is applied, the connecting mounting bracket 2 is not deformed and damaged. In addition, when the supporting legs 3 are fixed relative to the connecting and mounting frame 2 by adopting the structure, when the adduction connecting section 201 on the connecting and mounting frame 2 is formed by bending, the upper side surface and the lower side surface of the adduction connecting section are processed by surface processing to form concave-convex areas or frosted surface layers, so that greater friction force is provided in the clamping process, and the locking and fixing of the supporting legs 3 are more stable and reliable.
It should be noted that the adduction connection section 201 here extends from one end of the connection mount 2 to the other end, so that the support foot 3 can be fixed in any position with respect to the connection mount 2; when the position of the supporting leg 3 needs to be adjusted, the clamping plate and the main body of the supporting leg 3 can be converted into a relaxed state relative to the adduction connecting section 201 only by reversely rotating the bolt in a small amplitude, so that the translational adjustment action is conveniently carried out.
